New Technologies and Research Trends for Wireless, Mobile and Ubiquitous Multimedia

This special issue aims to provide the readers with a focused set of peer-reviewed articles to reflect the latest research results on advanced issues in convergence of wireless and mobile multimedia and ubiquitous computing technologies. It will include a number of related topics in multimedia processing, multimedia systems, mobile contexts, social networking services and ubiquitous computing environments. The papers will be peer reviewed by at least three independent reviewers and will be selected on the basis of their quality and relevance to the theme of this special issue.

In this paper, a cognitive closed access multi-element antenna-specific femtocell protocol is presented. Femtocell is considered as the preeminent solution for indoor coverage in long-term evaluation (LTE) and...

Base-band involved integrative modeling method (BIMM) is proposed for studying the transmission characteristics and bit error rate of the wireless communication, in which the transmitting and receiving antenna...

Static topology analysis is not sufficient for the dynamic vehicular ad hoc network. Understanding the evolving topology of vehicular ad hoc networkings (VANETs) caused by vehicle mobility is very important for r...

Many geographic routing algorithms have been proposed for vehicular ad hoc networks (VANETs), which have the strength of not maintaining any routing structures. However, most of which rely on the availability of ...

In this paper, differential modulation (DM) schemes, including single differential and double differential, are proposed for amplify-and-forward two-way relaying (TWR) networks with unknown channel state infor...

The recent development of vehicular networking technologies brings the promise of improved driving safety and traffic efficiency. Cooperative communication is recognized as a low-complexity solution for enhanc...

In the field of multiple input multiple output (MIMO) decoder, K-best has been well investigated because it guarantees an SNR-independent fixed-throughput with a performance close to the optimal maximum likelihoo...

This research describes a complete fuel-level monitoring system. The research started with the design and construction of a fuel-level sensor and then was followed by configuration of a remote Aplicom 12 GSM m...

Single-carrier frequency domain equalization (SC-FDE) has been shown to be an attractive transmission scheme for broadband wireless channels. However, its performance would degrade a lot if the channel is fast...

Identification of traffic flow is very important since it can help provide dynamic navigation and optimize the performance of vehicular ad hoc networks (VANETs). The existing ways for estimating the traffic st...
